The need to install a special hood over the stove is explained by the desire of users to get rid of extraneous odors and other fumes generated in the kitchen during the cooking process. At the same time, it is possible to ensure the required efficiency of indoor air purification only if certain rules and recommendations are followed, determined by the relevant regulations and standards. In this article we will introduce you to existing species exhaust structures and consider the order of their installation using the example of one of the most common models.

Types of kitchen hoods

Currently on the domestic market household appliances There is a wide range of kitchen hoods, which according to their design are divided into the following types:

• suspended design, which is one of the most convenient to install and practical exhaust devices, suitable for most ordinary users. With all the listed advantages, such a hood, however, is characterized by insufficient productivity;
• an exhaust device built into the walls or ceiling that provides the required efficiency in removing odors and fumes from rooms of a large area;
• an exhaust device designed in the form of a dome, the effect of which extends not only to the stove, but also to the working surfaces of the countertop located near it;
• the so-called “island” hood, mounted in the center of the kitchen space and providing air exchange throughout its entire volume (including above gas stove).

Auxiliary elements (air ducts)

As air channels through which unpleasant odors and fumes are diverted to the ventilation shaft hatch, special air ducts are used, made in the form of:

• corrugated pipe;
• rigid metal box;
• polyvinyl chloride pipes with smooth walls.

To the benefits corrugated pipes should be attributed to their flexibility and relatively low cost. The disadvantage of this budget option air duct is the need for constant care during operation. Used as an air duct metal box more convenient to use, but will require significant expenses from the contractor. The most optimal application option is considered PVC pipes, which is not only easy to install, but also does not require special care. Unlike other air ducts, this pipe is installed strictly above the hood.

Requirements for installation of the hood

Installation procedure kitchen hood will be considered by us using the example of the simplest hanging system, the installation of which requires the following requirements:

• The dimensions of the intake hole must correspond to the size of the gas stove, which ensures maximum effective removal polluted air;
• The height of the hood above the surface of the slab should not be less than 50-60 cm (the optimal distance from heating elements about 75-80 cm), which provides comfortable working conditions. If it is placed too low, the space for working with the stove will be limited, and the body of the device itself may overheat;
• The performance of the exhaust device must correspond to the volume of the room being served and ensure that the air in it is renewed at least 10 times a day. To calculate the exact value of this indicator, you need to decide on the basic dimensions of the kitchen room, and then use the following formula: V= SxHx10x1.3, where S and H are the area and height of the serviced room, respectively, and 10 is the minimum air exchange rate (1.3 is a correction factor);
• in the case when your home does not have a separate air shaft with access to the kitchen - it is recommended to use an exhaust device flow type with variable capacity, working on the principle of air mass recirculation.

Note! Connecting such hoods to an existing ventilation shaft may disrupt the operation of the entire exhaust system as a whole. In addition, it is not recommended to operate flow devices at full power (maximum performance mode) for long periods of time.

Installation procedure for the hood housing

Installing a hood over a gas stove involves phased implementation a whole range of work operations of the following nature:

• hang the case exhaust device directly above the stove;
• installation of exhaust air ducts, ensuring their reliable connection with the hood and the ventilation shaft hatch;
• eyeliner electrical supply, necessary for the operation of the exhaust device.

Important! When preparing a place to install a wall-mounted hood, the main thing is to ensure that it is positioned strictly symmetrically above the gas stove, since even the slightest deviation of the body to the side reduces the efficiency of the device by 10 - 20%.

Direct installation of the hood at the place of its operation is carried out in the following sequence:

• First, the fastening points are carefully marked, taking into account the location supporting elements on back wall housings (for these purposes it is most convenient to use a pre-prepared template);
• after that, in accordance with the markings, holes are carefully drilled in the wall into which dowels are driven;
• then the supports used to hang the body are fixed in the dowels using bolts;
• At the final stage of installation, all that remains is to hang the hood itself on the prepared supports (watch the video).

Note! During trial hanging, it is necessary to check the correctness of its orientation in various planes, which is verified using building level and can be adjusted by changing the position of the supports (their design allows for adjustment within small limits and allows you to hang the hood quite comfortably).

Installation of air ducts and power supply connections

• outlet channels for a wall-mounted kitchen hood are made up of relatively short and straight sections with a minimum number of bends, the radius of which should be chosen as large as possible;
• when using corrugated hoses as a discharge channel, their bending angle should not be less than 90 degrees;
• It is also not recommended to narrow the outlet section of the air duct, which can lead to increased noise;
• The hatch of the ventilation shaft to which the air duct is connected must be completely cleaned of all contaminants accumulated during its operation.

The operation of the exhaust mechanism requires an electrical network, the supply of which must be provided in advance. As a rule, products of this class are equipped with a cord with a plug, for connecting which a specially equipped socket with a grounding contact must be used.

Important! To avoid heating, such an outlet should not be located above the area where the hood is located.

Conclusion

From our description it follows that hanging a hood over a gas stove is not at all difficult, as you can see by watching any video on the relevant topic posted on the Internet. From these videos you will learn how to install a kitchen hood above the stove, as well as existing methods its connection to existing communications.

After purchase kitchen device Regarding air exchange, a logical question arises - how to install a hood over a gas stove in a private house with your own hands?

The relevance of the issue is due primarily to the fact that the modern kitchen is overcrowded household appliances. It is difficult to imagine a comfortable life without a microwave, refrigerator, multicooker or stove. The above list can be supplemented with a hood. How to install a hood and install this device will be discussed in today’s material.

Is a hood needed in a kitchen with a gas and electric stove?

Many owners are interested in whether a hood is needed in a kitchen with a gas stove (electric stove) in principle. The absence of an exhaust unit leads to several negative points.

The most unpleasant ones are in small room A huge amount of steam and smoke accumulates. With prolonged exposure, an increase in humidity is observed, which negatively affects the integrity of facing materials. During the cooking process, residual fumes and fat particles should be removed.

Types of devices

Before installing the hood, you need to decide specific type household appliance. The most popular types of devices today are:

• island;
• fireplace;
• corner;
• built-in;
• filtering.

Exhaust devices are equipped different types filters:

• Hoods for gas stoves with carbon filters. Are different effective elimination unpleasant odors, fat particles. They work primarily on the principle of air recirculation.
• Devices with a metal cleaning grid (grease trap). Suitable for gas stoves and kitchens that have access to a ventilation shaft. If it is missing, installation is not recommended. Their main advantage is the high-quality absorption of fumes and unpleasant odors. Equipped with aluminum filters.

If the hood in the kitchen is installed correctly and professionally, the air will be effectively cleaned of fumes through a filtration mechanism and then redirected back into the room. As for units equipped with grease traps, they do not filter contaminated oxygen, but remove it outside.

There are also universal models that provide not only filtration, but also air removal. It all depends on the specific requirements and criteria.

Some apartments do not allow you to connect an exhaust hood to ventilation system. For such cases, it is necessary to install household devices that operate on the recirculation principle (air filtration and redirection back into the room). What system is needed in each specific case is up to the owners to decide, but we recommend purchasing units with carbon filters.

Efficiency and performance of the hood

A modern hood over a gas stove is capable of providing different levels of air exchange (the value can vary between 200-1400 cubic meters per hour). But it is not always worth purchasing hoods with maximum power. An air pumping speed of 500 m3/hour is considered sufficient.

The calculated efficiency value is multiplied by the volume of the room and by 10. The final result is multiplied by 1.3 (this is a small reserve that everyone should have household appliance). At the output, we obtain a performance value sufficient to purify the air at medium loads (the device does not operate at maximum speed and unpleasant noise does not occur). This value The efficiency will be optimal.

It is customary to indicate in the device passport the power of vapor removal into the ventilation air duct. If the kitchen appliance operates in 2 modes, then the power of the second will be 60% of the passport data (up to 40% is lost when passing through the filter).

Absolutely silent hoods does not exist. But you can always choose an option with optimal values noise and performance. Acceptable level is 36 dB during operation. Systems powered by an electric motor installed in a soundproof plastic box can boast such values.

How to install a hood in a closet

To ensure that installing a hood over a gas stove gives the owner a minimum of hassle, several things should be taken into account: important points. Are taken into account individual characteristics specific model of kitchen appliance, type of filters, location of the ventilation shaft, etc.

Installation of a firecracker (anti-return mechanism)

Let us dwell in more detail on the features of installing an air cracker. First of all, it is worth installing an aluminum or galvanized product. A wide range of such solutions are now on sale. It is mounted directly in front of the ventilation shaft.

To ensure maximum convenience, it is better to install a hood above a gas stove in a private house in a cabinet located above the base of the hob. Installing the housing into a kitchen unit does not cause any difficulties. Then the holes and cracks are filled polyurethane foam, thanks to which the device is fixed very securely. Due to this, the resonance of the household appliance during its operation is leveled out.

It is not recommended to install the firecracker immediately. First, you should place the exhaust device and mark the places where the holes will be located. For convenience, the cabinet is first removed, and the necessary cuts and shapes are made inside.

Cutting inside kitchen set It will be simplified if the diameter of the hole is designated by several through holes (in a circle). After this, a jigsaw is inserted and a hole is made with its help. They should be on every shelf, if there are any in the closet. This will simplify the installation of the air duct.

Duct installation

Installation of the air duct is carried out in the following sequence:

When installing, it is necessary to minimize the number of bends in the corrugation or plastic pipe. This will ensure good traction since cornering reduces power by an average of 10% in each knee.

How to install a hood: standard installation sequence

The owners are interested in: how to properly install a hood over a gas stove in cases where it is impossible to place the device above hob in a kitchen set? Obviously, it has long been not always practical to place a unit in a furniture structure, since under the influence of humidity these accessories deteriorate and lose their original aesthetic appearance.

Almost all modern wall cabinets are narrow, which excludes the possibility of placing wide devices in them. The recommended height of the hood above the gas stove is 650-750 mm.

Installation is carried out in several stages:

1. With help metal corners a rectangular structure is formed. This frame is used to support the body of the exhaust device.
2. Self-tapping screws are ideally suited as fasteners for fixing to the wall.
3. The hood is connected to the electrical network.

Gas workers emphasize the need to ground fans so that residual voltage is discharged into the external space. The distance from the gas stove to the hood is indicated in the passport data for each unit model.

Important points

Experts identify several important aspects, worthy of attention at the stage of installation of the device.

1. Filters are cleaned or replaced every 2-3 months (taking into account the intensity of use). A large number of grease and residual substances may cause the structure to catch fire.
2. The installation height of the hood above the gas stove is 65-75 cm. If you install the device too low, it will not cope with the load and elevated temperature, which is fraught with failure of the unit.
3. The “golden” rule for selecting exhaust hoods is that the hood should be the same.
4. The kitchen appliance is connected to an electrical network independent from the main part of the house.

During installation, observe safety precautions. Preventative cleaning of the hood from burning is carried out once every 2 quarters, under medium loads. Knowing at what height it is better to mount the device, you can save a small amount on the services of specialists.

The hood is one of the most important elements of kitchen appliances. The comfort of being in a place depends on its choice and placement. kitchen area, preservation of the coating of walls, ceilings and furniture, aesthetic appearance kitchens - the modern hood has long been important element decor.

The exhaust system is especially relevant in a kitchen with gas stoves - unlike other types of hobs, the gas heats the air to a greater height and releases when it burns harmful products decay, burns oxygen.

During intensive cooking, air purification is simply necessary in the room.

When deciding how to install a hood over a gas stove, you should be especially careful about the type of exhaust system; not every design provides optimal operation in rooms with gas.

Primary requirements

Functionality

A flow hood will remove polluted air, a circular hood will clean the polluted air with filters and return it to the room

All hoods are divided into two large groups: circular and flow-through; in the first, air is passed through filters and returned back. At the same time, the room will remain high humidity, many harmful decomposition products during gas combustion, air with low oxygen content - content standards harmful substances may be exceeded.

When using flow-through types, polluted air is removed outside the kitchen area and replaced with fresh air - this type exhaust systems for gas hobs preferable.

Aesthetics

The exhaust system should fit optimally into the interior without disturbing the appearance of the kitchen. To do this, hoods are built into furniture (cabinets above the stove), and the color of the work surface, body, or design is selected to match the style of the kitchen.

Many people forget about this, installing especially popular ones in Lately modern inclined models in high-tech style made of glass and metal, with black glossy surfaces, in any kitchen, often reminiscent of a classic or Provence style with light wood-look furniture.

Efficiency

The exhaust system in the kitchen should eliminate as much as possible Negative consequences when cooking food: foreign odors, water vapor with tiny droplets of fat, particles of soot and soot in the air, high humidity. The hood for a gas stove must be correctly installed above the hob and have the appropriate power and performance.

Classification

By design All existing hoods can be divided into several groups.

Flat

Flat options have a minimalist design and will not stand out from the rest of the kitchen elements

A very common type, a flat worktop is located parallel to the hob. They take up little space, the design is mainly used in circular types.

Dome

Such models capture a larger volume of air during cooking.

One of the most common designs, in appearance they resemble a dome lowered over the hob along a square pipe in the upper part. In almost all designs, this pipe is part of the air duct, and dome hoods are built into a flow-through exhaust system - such designs are very rarely used in circular types.

Retractable

Retractable models are practical, but have a short length, so they capture less air during operation

To increase service area working surface hoods are often increased by a retractable module. Typically, such models are built into the lower part of a wall-mounted kitchen cabinet, which can hide an air duct or, in the case of circular ones, leave space for placing kitchen accessories. Retractable - very convenient design when installing an exhaust system in small kitchens.

Corner

Corner models are not so widely used, so the choice of design and functionality may differ from standard options

Placed in the corner of the kitchen, designed for a gas stove turned at an angle of 45 degrees to the main wall. The working surface of the hood has the shape of a square with a truncated corner.

Island

Island options are becoming exclusively in kitchen islands

Designed to be placed in large kitchens, if the hob is located in the center of the room. Typically, the hood is lowered above the hob on a square duct.

Oblique

Inclined models have a stylish appearance and standard functionality

Modern solution kitchen exhaust systems, in which the working panel is located at an angle to the hob. This allows the inclined model, with the same area as the flat horizontal one, to occupy less in the kitchen free space. The design looks most aesthetically pleasing modern kitchens hi-tech style.

Tabletop

Just recently appeared the new kind hoods, saves space for wall cabinets or shelves

The device is mounted in the table next to the hob. During operation, its suction working panel extends vertically upward and air is pumped out.

Hoods are classified according to installation method as follows:

• Hanging. It is fixed directly above the stove using cables or on the air duct.
• Built-in. Installed in kitchen furniture below the hanging cabinets.
• Wall-mounted. Attached to the wall above the hob.

Installation height

The installation height depends on the average height of the person in the family

Main parameter during installation, the distance between the hood and the gas stove should not be less than 750 mm. and no more than 900 mm.

This distance is selected taking into account the ergonomic characteristics of the housewife and depends on the power of the hood - more powerful structures can be placed higher. Also, the installation height of the hood above the gas stove in many cases directly depends on the manufacturer’s recommendations, which must be followed first (these requirements are described in the instructions for the device).

Size

The second main parameter is that the width should not be greater than the width of the hob. If structurally it rises to a height greater than the recommended one, it dimensions or suction power should be increased.

When deciding how to properly install a hood over a gas stove when using an inclined model, they usually focus on the lower edge of the air intake - minimum distance there should be 550 mm to the slab.

One more important parameter The hood is its depth; usually this parameter corresponds to the dimensions of the hob and is typical for its width.

Installation of exhaust systems

Installation may vary depending on system type

Installing a kitchen hood with your own hands is quite simple if you follow the instructions and work procedure. Manufacturers often produce kitchen hoods that combine two operating modes - circular and flow-through.

Installation of a circular hood

The use of circular mode in kitchen areas with a gas hob is not very a good decision. An autonomous circular hood above a gas stove will not be able to provide the necessary comfort in the kitchen; its carbon filters, unlike electric stoves, will quickly become clogged with gas combustion products, which will lead to additional economic costs.

Installing a circular kitchen hood usually does not cause big problems: it can be attached directly to a straight wall or in a corner, built into furniture, lowered above the hob through a pipe or on cables. The sequence of work when installing it on the wall is as follows:

• The connection location is pre-determined; if the nearby socket is not very suitable or is located far away, the point is moved. In this case, it may be necessary to chip the walls and install new socket with wiring for connection.
• In the wall on required height Attachment points that define the location of the hood are marked, holes are drilled using a hammer drill and dowels are driven in. It is important to control the correct installation using a building level - the working surface of the hood should be located strictly horizontally above the stove.
• The hood is screwed to the wall with screws through the mounting holes, if it interferes gas pipe, it extends from the wall and is attached to long studs with nuts. You can also place a block of appropriate thickness between the wall and the hood and attach the hood to it or the wall with dowels using long screws through the beam.

Installation of flow hood

When deciding how to hang a hood over the stove, you should know that a flow hood will require the installation of an air duct system to connect it to ventilation hole a common house shaft, or an external air outlet in a wall, window or ceiling.

Installation of air ducts with the installation of a hood is easy to do with your own hands if you follow a certain procedure.

Required tools and materials

Selection of air ducts. For the installation of flow-through systems in everyday life, two types of air ducts are most often used: corrugated aluminum or plastic with a square or round cross-section.

Example of aluminum corrugated pipe

The question of how to install a hood in the kitchen worries many today. When renovating their kitchen, people in most cases think about creating a more efficient ventilation system, because this is not just convenient, but even necessary.

A person who prepares food regularly spends about five hours a day in the kitchen and breathes harmful fumes, including smoke and fumes.

In addition, during cooking, tiny particles and fats are released from food into the air, which also adversely affects human health.

The only way out in this situation is to purchase and install a hood, since neither traditional systems ventilation, nor simple airing will not provide the required effect. How to properly install a hood in the kitchen will be discussed in this article.

Selecting a hood

One of the most important systems In a person’s home, ventilation is what ensures the comfort of his life. In a sufficiently ventilated room, the air is clean and fresh, which makes it simply pleasant to be here, while stuffiness can cause negative reactions in the body, including general weakness and dizziness.

Kitchen hoods are one of the main ventilation units, since cooking is associated with elevated air temperatures and harmful emissions, including very unpleasant odors.

The main task of the hood is to clean the air in the room. And the cleaning process itself can occur in different ways. The mounting of the kitchen hood directly depends on this. So, there are two types of operation of modern hoods.

Types of hoods

1. The simplest hood device works on the principle of air recirculation. In this case, the air is not removed outside the room, but passes through special filters and returned back. Sometimes such hoods are also called filter hoods or hanging hoods (see also the article about a hanging hood for the kitchen).

Advice! If the ventilation shaft is clean and “pulls” well, then you can remove the valve from the hood and allow it to work with the engine turned off. This is possible in houses with controlled ventilation.

Connecting the hood to ventilation

Since installing a hood in the kitchen is not difficult, you can handle this procedure yourself. But it's better to take an assistant.

1. We attach the hood to the wall and mark its future position with a pencil. If you are planning to change your kitchen furniture, you should consider installing a hood in a wall cabinet.
2. We drill the walls with a hammer drill for the dowel. You shouldn’t mess around here, since the structure must be “tightly” fixed.

It is well known that exhaust devices installed above kitchen stove, are used to remove exhaust gases and unwanted odors arising during the cooking process. The efficiency of air purification and the possibility of keeping it in the kitchen largely depend on the model of the exhaust device you choose. comfortable conditions for accommodation. But before you hang the hood over the stove, you should thoroughly study the basic requirements for its installation technique. This issue is of particular importance in a situation where you have a gas stove installed in your kitchen, the operation of which is always associated with increased risks.

It is believed that the method of installing an exhaust device is quite simple and can be mastered by anyone. That is why in this article we would like to introduce you to the technique of installing kitchen hoods with your own hands.

Types of exhaust devices

All known types of exhaust devices can be divided into two large groups:

• circulation devices with built-in carbon filter;
• hoods built into the existing air exhaust system.

In models of exhaust equipment with a filter element, air is purified by forced circulation within the device.

In this case, contaminated air first enters the system, and after cleaning in the built-in filter, it is returned to the kitchen space. Similar models exhaust devices are most often installed in small kitchen areas.

In kitchens big size It is advisable to use hoods with a forced air intake mechanism, the output of which is connected to current system ventilation. With the help of such partings, polluted air is removed from kitchen space outside (outside the premises). The operating efficiency of such exhaust devices is noticeably higher than that of partings with forced circulation air, so they are most often installed in kitchens with a large number of sources of pollution.

For successful installation DIY hoods you will need to follow the following rules:

• the distance from the slab to the intake casing (the plane of the inlet) of the hood should not be less than 65 centimeters;
• the dimensions of the intake casing should approximately correspond to the dimensions of the gas stove;
• used to connect the hood electric outlet should not be located directly above the stove;
• When connecting the hood to the air duct, its outlet pipe should have a minimum of bends.

Installation

Installation of a hood with a built-in carbon filter will not require any special skills from the performer and special effort. To install it you will need good level, with the help of which control points for hanging the device are marked at the selected height, and then holes are punched for the fastening elements using a puncher.

Fixing the hood on the wall or wall cabinet It is made using special hooks that securely hold it at the suspension points. When installing an exhaust device on the front part of the kitchen unit, it is best to use niches that are always available in wall cabinets to place it.

The body of the hoods with connection to the air vent is fixed using the same fasteners (hooks), with the only difference being that their installation location must be “tied” to the ventilation hole. After fixing the device in the selected location, an air duct channel is attached to its outlet (ordinary plastic pipes can be used as such a channel).

The main thing is that the pipes you use are sized to match the diameter of the air intake hole in the wall, which will allow you to avoid losses in pumping power. Upon completion of all installation procedures, you should conduct a test check of the operation of the equipment, which will allow you to ensure that it has been installed correctly.

If you need a separate outlet to connect the hood, all the wires supplying power to it can be “hidden” in a special cable channel. In addition, electrical wiring can be hidden under sheets decorative material used to decorate your kitchen.

Note! It is necessary to provide a special protective device(the so-called “automatic machine”), which ensures that the equipment is turned off in the event of an emergency.

We really hope that our article will help you figure out how to hang a hood over the stove in such a way that you will forever get rid of unpleasant odors in the kitchen and be able to enjoy fresh and clean air.
